The 10 years to the end of 2019 have been confirmed as the warmest decade on record by three global agencies.
According to Nasa, Noaa and the UK Met Office, last year was the second warmest in a record dating back to 1850.
The past five years were the hottest in the 170-year series, with the average of each one more than 1C warmer than pre-industrial.

The Met Office says that 2020 is likely to continue this warming trend.
2016 remains the warmest year on record when temperatures were boosted by the El Niño weather phenomenon.
